[Factors involved in microbial colonization of acrylic resins].

Unlabelled: The objective of this study was to evaluate the effect of polishing technique and the polymerisation type on the microbial colonization of acrylic resins.

Material And Methods: The studied resins were: Castapress/Vertex, Prothyl Hot/Zermack, Duracryl Plus/Spofa Dental, Vertex-Soft/Vertex, Superacryl Plus/Spofa Dental. Ten specimens, two for every resin, presenting dimensions of 50/25/2 cm were done.

[Surface characteristics of the acrylic resins according to the polishing methods].

Aim: The objective of this study was to evaluate the effect of the polishing technique and glazing on the porosity of the dental resins.

Material And Methods: The studied resins were: Castapress/Vertex, Prothyl Hot/Zermack, Rapid Simplified/Vertex, Duracryl Plus/Spofa Dental, Vertex-Soft/Vertex, Superacryl Plus/Spofa Dental. Thirty specimens, five for every resin, of 50/25/2 cm in size were done.

[Resilient attachments--biological treatment solution for unilateral partials].

The attachments recommended for a unilateral free-end distal extension partial denture assure the comfort for the patient because don't need a cross arch stabilization. One of the most used resilient attachment is represented by FM Hinge (New Anchorvis), an extracoronal, hinge resilient distal extension attachment. It is formed by two elements: a metallic female, designed for adhering into the framework of the denture base and a male, made of fully combustible plastic high fusing for casting to precious and semiprecious alloys.

Aesthetic goals in porcelain fused to metal prosthetic appliances.

Unlabelled: The ultimate goal for ceramic fused to metal restoration is the creation of a perfect aesthetic integration of the restoration with healthy tissues.

Material And Method: The study included a group of twenty-one patients. Sixteen of them were partial edentulous patients and five presented dental lesions or chromatic modifications of the dental tissues.

[Study concerning the influence of the casting parameters of dental alloys on the cast prosthetic rehabilitation].

Unlabelled: The integration of a cast rehabilitation into the oral environment and its clinical longevity are mainly determined by the accuracy reproduction of the technological parameters. The aim of this study was to evaluate the structural defects induced by the modification of the technological conditions of casting the conventional and titanium alloys.

Material And Method: We used 35 cast prosthetic rehabilitation, divided into 7 groups.

[A maxillary premolar reconstruction with a glass fiber reinforced post].

This paper presents the case of a 37 years old female patient who needed a reconstruction of an endodontic treated' second maxillary premolar. The patient presented large areas of occlusal abrasion caused by bruxism, therefore the solution consisted of a reconstruction with a non-metallic post reinforced with glass fibers. In such cases, the excessive occlusal forces developed by bruxism can produce a radicular fracture if the tooth would be reconstructed with a rigid metallic post.
